The NIH is the National Institute of Health in Bethesda Maryland.  It is a large medical center that does research and study on all types of medical conditions and diseases.   It is funded by the National gov.    Dr. Deborah Merke is doing research and conducting a study on people with CAH.   I went there last summer they did alot of blood test exam health history I met with Dr. Merke and one of her fellows.   It was determined that my Prednisone could be reduced slightly I have been feeling  very well on less Pred.   If you google NIH all the info about the facility is there.
